Tip: It is advised that you complete the quest "Visit the Sheriff" together with all the following missions before attempting any other main storyline quests available at this point, including this one.

After you return to Wellspring to complete the quest "Wellspring Bound", Mick will greet you in his garage, and this quest will be given to you. It is a very simple quest. Just do as it says and go see the mayor.

It turns out there is a disturbing rumor that some bandits are refining pure Feltrite, and in their hands it might be dangerous, and so the Mayor needs someone like you to take a closer look to the problem. At this point you will be given the quest "Feltrite Crater".
